REC was asked to determine the most effective treatment process arrangement to replace an existing lagoon based pretreatment system for a unique food processing wastewater. The food processing facility utilizes soy bean husks and generates a wastewater that is high in COD, TSS, TKN and Sodium. Previous analyses had indicated that a higher than normal fraction of soluble non-biodegradable nitrogen. REC arranged to have the Siemens Energy laboratory in Rothschild, WI operate the pilot unit as designed by REC. The pilot unit was based on a 4-stage Bardenpho process. Once the pilot unit achieved stable operation, REC had the Siemens laboratory perform a series of tertiary treatment methods to include a carbon isotherm analysis; filtration; advanced oxidation with chlorine, peroxide and ozone with UV; coagulation jar tests with ferric chloride; and a BioMag and CoMag analysis. Data to date indicates that it is possible to remove the large fraction of soluble non-biodegradable nitrogen by use of the 4-stage Bardenpho (possibly reduced to a 2-stage MLE process) in conjunction with coagulation and tertiary advanced oxidation. Additional testing is currently in process
